winrt: Do not lose initial data for TCP connections

When a client connects and sends data immediately it was possible that
initial data was lost as the state was set too late. If the callback was
called before the state was set the socket engine just discarded the
data. So the state has to be set before the callback is registered.

The new implementation needs a list of pending read operations. It can
happen that the "readyRead" callback is triggered directly while
"put_Completed" is called. The callback reassigns readOp which causes a
"function not implemented" exception when it jumps back to the
"put_Completed" call in "initialize"
